You are not serving me. You are serving Prabhupāda; the society is founded by him. We are all serving Prabhupāda; thereby, we're serving Mahāprabhu and Kṛṣṇa. When you are in the society founded by Śrīla Prabhupāda and serving under the order of some authorities—temple president or secretaries, etc.—you serve Prabhupāda. But it is essential that you be linked to Prabhupāda by one of his disciples; then you will be linked.
